Bis(5-chloro-2-hydroxyphenyl)methane is a fungicide and is very effective against many celluloytic fungi, such as Penicillium, Aspergillus,Cladosporium and Trichoderma sp. It is a phenolic pesticide and undergoes photodegradation in the presence of visible-light absorber photosensitizer riboflavin.

Bis(5-chloro-2-hydroxyphenyl)methane can be used as a starting material to synthesize methyl aluminium-(2,2′-methylene-p-chloro-bisphenoxide), which is used as a catalyst for the ring opening polymerization (ROP) of cyclic esters. It can also be used as an organic building block to prepare phosphomides substituted with aminoacid esters for various biological studies.

The product is not intended for use as a biocide under global biocide regulations, including but not limited to US EPA′s Federal Insecticide Fungicide and Rodenticide Act, European Biocidal Products Regulation, Canada’s Pest Management Regulatory Agency, Turkey’s Biocidal Products Regulation, Korea’s Consumer Chemical Products and Biocide Safety Management Act (K-BPR) and others.
